Check the Parking
Brake Warning Light by
placing the ignition
switch to the ON posi-
tion (do not start the
engine).
This light will be illuminated when the
parking brake is applied with the igni-
tion switch in the START or ON posi-
tion.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.If the Parking Brake Warning Light
remains on after the parking brake is
released while engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.Anti-lock Brake System (ABS)
WARNING
An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
maneuvers. Even though vehi-
cle control is improved during
emergency braking, always
maintain a safe distance
between you and objects ahead
of you. Vehicle speeds should
always be reduced during
extreme road conditions. The
braking distance for cars
equipped with ABS or ESC may
be longer than for those without
these systems in the following
road conditions.

Driving your vehicle
Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle’s brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.

ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
If this light stays on, your vehicle may
have a malfunction with the ESC
system. Have your vehicle checked
by an authorized HYUNDAI dealer
as soon as possible.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
• When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This
is normal and it means your ESC is
active.
• When the ESC activates, the
engine may not respond to the
accelerator as it does under rou-
tine conditions.
• If the Cruise Control was in use
when the ESC activates, the cruise
control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow. See “Cruise Control System”
later in this chapter.• When moving out of the mud or
driving on a slippery road, the
engine rpm (revolutions per
minute) may not increase even if
you press the accelerator pedal
deeply. This is to maintain the sta-
bility and traction of the vehicle and
does not indicate a problem.

Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires.
Always carry emergency equipment.
Some of the items you may want to
carry include, tow straps or chains, a
flashlight, emergency flares, sand, a
shovel, jumper cables, a window
scraper, gloves, ground cloth, cover-
alls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
✽NOTICE
Do not install studded tires without
first checking local and municipal
regulations for possible restrictions
against their use.
Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
WINTER DRIVING

Driving your vehicle
WARNING
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.

Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in section 7. We recommend that the
system be checked by an authorized
HYUNDAI dealer.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, we recommend that you
consult an authorized HYUNDAI
dealer.
Check spark plugs and igni-
tion system
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.

Driving your vehicle
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
If there is a risk the parking brake
may freeze, apply it only temporarily
while you put the shift lever in P
(automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tire chains, tow straps or
chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a win-
dow scraper, gloves, ground cloth,
coveralls, a blanket, etc.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign objects or
materials which prevent cooling of
the engine, in the engine compart-
ment, may cause a failure or com-
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

IF THE ENGINE WILL NOT START
If the engine doesn't turn over
or turns over slowly
• Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transaxle vehicle. The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
• Check the battery connections to
be sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the engine turns over nor-
mally but doesn’t start
• Check the fuel level and add fuel if
necessary.
If the engine still does not start, call
an authorized HYUNDAI dealer for
assistance.

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1.Pull off the road and stop as soon
as it is safe to do so.
2.Place the shift lever in P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle) and set the parking brake. If
the air conditioning is ON, turn it
OFF.
3.If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running or
the steaming has stopped. If there
is no visible loss of engine coolant
and no steam, leave the engine
running and check to be sure the
engine cooling fan is operating. If
the fan is not running, turn the
engine off.4.Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5.If engine coolant is leaking out,
stop the engine immediately and
call an authorized HYUNDAI deal-
er for assistance.

WARNING
While the engine is
running, keep hands,
clothing and tools
away from the moving
parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.
